Description

Technical Field

[0001] This utility model relates to the field of plastic mold blank technology, specifically an auxiliary clamping mechanism for plastic mold blanks. Background Technology

[0002] The mold blank is the skeleton of the entire mold, used to position the various components of the mold, including the mold core, connecting rods, heating rods, runners, cooling devices, and ejector pins. The cost of the mold blank usually accounts for about 30% of the total cost of the mold. It is manufactured by specialized large mold blank factories and is standardized. Mold manufacturers can customize mold blanks from mold blank factories according to their needs.

[0003] In the prior art, such as the plastic mold blank proposed in patent application number "CN202223004882.8", a fixed mold push plate is included. The outer walls on both sides of the top side of the fixed mold push plate are provided with guide holes. The inner walls of the guide holes are inserted with guide rods. The bottom outer walls of the guide rods are fixed with fixed templates. The top outer walls of the guide rods are sleeved with movable templates. The movable templates are located directly above the fixed mold push plate. A circular groove is provided on one side of the outer wall of the fixed mold push plate. A circular hole is provided on the inner wall of the other side of the circular groove. A movable rod is slidably connected to the inner wall of the circular hole.

[0004] However, in the aforementioned patent, the position of the plastic mold blank is unstable during processing, which affects the processing of the plastic mold blank. It is not convenient to clamp and fix the position of the plastic mold blank according to the needs. After the processing of the plastic mold blank is completed, it is necessary to manually remove the processed plastic mold blank, which is time-consuming and labor-intensive, and affects the processing effect of the plastic mold blank.

Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0024] An auxiliary clamping mechanism for a plastic mold blank includes an operating table 1, a rotating component, a clamping component, and a pushing component. Two control blocks 2 are provided on the upper surface of the operating table 1. A pair of bolts are threaded on the lower end of each of the two control blocks 2. The lower ends of the two pairs of bolts are threaded inside the operating table 1.

[0025] The rotating assembly includes a rack 4 fixedly mounted on the movable end of the first electric push rod 3, a fixed block 5 fixedly mounted on the upper surface of the operating table 1, a sliding groove 6 opened on the upper surface of the fixed block 5, the lower end of the rack 4 slidably mounted inside the sliding groove 6, a transmission gear 7 meshing on the upper surface of the rack 4, a rotating rod 8 fixedly mounted in the middle of the transmission gear 7, and the rotating rod 8 rotatably mounted inside the two control blocks 2.

[0026] like Figure 1 , Figure 2 and Figure 4 The bolt thread is inserted into the control block 2 and the operating table 1. The movable end of the first electric push rod 3 drives the rack 4 to slide inside the sliding groove 6. The movement of the rack 4 drives the transmission gear 7 to rotate, so that the rotating rod 8 rotates between the two control blocks 2.

[0027] The clamping assembly includes a connecting block 9, which is fixedly disposed in the middle of the rotating rod 8. A second electric push rod 10 is fixedly disposed on the upper surface of the connecting block 9, and a first clamping block 11 is fixedly disposed on one side of the connecting block 9.

[0028] like Figure 4Since the connecting block 9 is fixed in the middle of the rotating rod 8, the first clamping block 11 is fixed on one side of the connecting block 9, and the second electric push rod 10 is fixed on the upper surface of the connecting block 9.

[0029] The movable end of the second electric actuator 10 is fixedly provided with a second clamping block 12, and a limiting groove 13 is opened on one side of the connecting block 9. One side of the second clamping block 12 slides inside the limiting groove 13.

[0030] like Figure 4 The second clamping block 12 is slid inside the limiting groove 13 by the movable end of the second electric push rod 10, so that the second clamping block 12 moves toward the first clamping block 11.

[0031] The second clamping block 12 slides on one side of the connecting block 9, and a plastic mold blank body 14 is provided between the first clamping block 11 and the second clamping block 12.

[0032] like Figure 1 and Figure 4 The position of the plastic mold blank body 14 is fixed by clamping the first clamping block 11 and the second clamping block 12.

[0033] The push component includes a groove 15, which is formed on the upper surface of the operating table 1. A third electric push rod 16 is fixedly installed on the upper surface of the operating table 1.

[0034] like Figure 1 Since the third electric actuator 16 is fixed on the upper surface of the operating table 1, a groove 15 is opened on the upper surface of the operating table 1.

[0035] The movable end of the third electric actuator 16 is fixedly provided with a take-up and release frame 17. The take-up and release frame 17 is slidably disposed inside the groove 15. Movable blocks 18 are fixedly disposed on both sides of the take-up and release frame 17, and the two movable blocks 18 slide on the inner side of the groove 15 respectively.

[0036] like Figure 1 The movable end of the third electric actuator 16 drives the take-up and release frame 17 to slide inside the groove 15, so that the two moving blocks 18 slide on the inner side of the groove 15 respectively, controlling the position between the take-up and release frame 17 and the groove 15.

[0037] The working principle of the auxiliary clamping mechanism for plastic mold blanks provided by this utility model is as follows:

[0038] The movable end of the second electric push rod 10 drives the second clamping block 12 to slide inside the limiting groove 13. The first clamping block 11 and the second clamping block 12 cooperate to clamp and fix the position of the plastic mold blank body 14. The movable end of the first electric push rod 3 drives the rack 4 to move, so that the rack 4 meshes and drives the transmission gear 7 to rotate, so that the rotating rod 8 rotates inside the two control blocks 2, driving the connecting block 9 to rotate, placing the plastic mold blank body 14 inside the receiving frame 17. The movable end of the third electric push rod 16 drives the receiving frame 17 to slide inside the groove 15, and removes the plastic mold blank body 14.

[0039] Compared with related technologies, the auxiliary clamping mechanism for plastic mold blanks provided by this utility model has the following beneficial effects:

[0040] Since the rotating component of this utility model includes a first electric push rod 3 and a rack 4, and the clamping component includes a connecting block 9 and a second electric push rod 10, the position of the plastic mold blank body 14 is clamped and fixed by the cooperation of the first clamping block 11 and the second clamping block 12. The connecting block 9 is rotated by the rotating rod 8, so that the plastic mold blank body 14 is placed inside the receiving frame 17, which is convenient for clamping and fixing the position of the plastic mold blank body 14 according to the needs.

[0041] Since the pushing component includes the groove 15 and the third electric push rod 16, the movable end of the third electric push rod 16 drives the take-up and release frame 17 to slide inside the groove 15, which improves the processing effect of the plastic mold blank body 14.

[0042] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
